The Flexon rib reinforcements will keep the leading edge open for easy inflation.
The most common reason for a bad launch is a bad layout!
5.1.2 ALPINE LAUNCH OR FORWARD LAUNCH
The NRG PRO II has very good launch behaviour in no wind conditions.
For the best results we recommend the use of the following techniques: Lay out the glider
and position yourself in the centre of the wing with the lines almost tight.
With a positive and constant force inflate the wing holding only the A-risers, and smoothly
increase your running speed. The wing will quickly inflate and settle above your head without
the tendency to stick behind.
After you leave the A-risers, apply about 15% brakes and the NRG PRO II will gently lift you
off the ground.
5.1.3 STRONG WIND AND REVERSE LAUNCH
The NRG PRO II has a lot of lifting power and care should be taken in strong wind. It is
advisable to have an assistant hold you when attempting a strong wind launch. It also helps
if you walk towards the wing and leave the A-riser just before the glider gets above your
head.
The assistant should let you walk in under the wing on inflation rather than resist the inflation;
this reduces the tendency of the glider to lift the pilot prematurely.
5.1.4 TOW OR WINCH LAUNCHING
All APCO gliders are well suited for winching and have no bad tendencies on the winch.
With towing it is important to have the wing above your head on launch and not to try and
force a stalled wing into the air. This is especially important if the winch operator is using
high tension on the winch. Very little brake if any need be applied on launch and during the
tow. Directional changes can be made with weight shift rather than brakes. While on tow,
the brake pressure will be higher and more force may be needed to make corrections than
in normal flight.
For all our gliders we recommend using tow accelerating system. There are different types
existing on the market. Please check with your dealer or tow operator for the recommended
tow accelerator system. Use of it will eliminate any chance for accidental stalling on tow.
5.2 FLIGHT TECHNIQUES
5.2.1 FLYING SPEED
Indicated trim speed is dependent on the amount of brake the pilot is using, wing loading,
altitude above sea level and the accuracy and make of speed probe. The speeds recorded
